Answer 1

Well when you multiply it, it would equal 90 and 5*18 is 90 then you subtract 40 and you would get 50

SO YOUR ANSWER IS >>18<<

Answer 2

Let x be the unknown number.
multiply X by 5 : 5x
then subtract 40 from it
5x - 40
this should equal 50
5x - 40 = 50
solve for x:
add 40 to both sides of the equation
5x = 90
divide both sides of the equation by 5:
x = 18
